Sclerotic scattering illumination during phototherapeutic keratectomy for better visualization of corneal opacities

Four Cases of Acanthamoeba Keratitis Treated With Phototherapeutic Keratectomy

“…Illuminationassisted PTK using sclerotic scattering illumination during the procedure was reported to be an option for achieving better visibility for opacified tissues and avoiding excessive ablation. 4 In cases 2 and 3, this illumination technique was performed and no additional ablation was required.

The Sclerotic Scatter Limbal Arc Is More Easily Elicited under Mesopic Rather Than Photopic Conditions

“…Sclerotic scatter is a sensitive technique that is effective for spotting corneal lesions [ 4 ] that may otherwise be overlooked. It easily reveals both the presence and the extent of corneal changes [ 5 , 6 ], however subtle these may be [ 3 ]. It does not, however, provide information as to the depth of the abnormality within the cornea and must therefore be combined with direct illumination with the slit beam [ 4 ].…”
